Amino Acid Balance During Physical Inactivity

The aim is to assess the impact of forearm cast immobilization on muscle amino acid balance and forearm glucose uptake. In addition, we will evaluate how high-fat overfeeding during immobilization will modulate muscle amino acid balance and forearm glucose uptake.
